UC Berkeley biologist Robert Full shares his fascination with spiny cockroach legs that allow them to scuttle at full speed across loose mesh and gecko feet that have billions of nano-bristles to run straight up walls.His talk, complete with wonderful slow-mo video of cockroach, crab and gecko gaits, explains his goal of creating the perfect robotic "distributed foot."

He's using his research to design the perfect robotic "distributed foot," adding spines, hairs and other parts to metal legs and creating versatile scampering machines.

He's helped create robots, such as Spinybot, which can walk up sheer glass like a gecko -- and he even helped Pixar create more realistic insect animations in the film A Bug's Life.
